“Kara gains a new ally when the lightning-fast superhero The Flash (Grant Gustin) suddenly appears from an alternate universe and helps Kara battle Siobhan, aka Silver Banshee, and Livewire in exchange for her help in finding a way to return him home.”

Do you think they’ll race like Superman raced The Flash in the comics? That would be kinda fun to see, but even if they don’t, I’m sure the episode will deliver something great for the fans.

I imagine this is the first of a few team-ups we’ll eventually see in the DC TV universe. I bet the next time we see these two heroes team up, it will be in an episode of The Flash. The crossover episode airs on CBS on Monday, March 28 at 8pm.
